Question

谁给我总结一下硝酸和金属反应的规律.

Answer 1

4Zn + 10HNO3=4Zn(NO3)2 + 5H2O + N2

4Zn + 9HNO3＝Zn(NO3)2 + 3H2 + NH3

3Zn + 7HNO3=3Zn(NO3)2 + ZH2O + NH2OH

Mg + 4HNO3 (浓 )=Mg(NO3)2 + 2NO2 + 2H2O

3Mg + 8HNO3(8M)=3Mg(NO3)2 + 2NO +4H2O

4Mg + 10HNO3(2M)=4Mg(NO3)2 + N2O + 5H2O

4Mg + 10HNO3(lM)=4Mg(NO3)2 + NH4NO3 + 3H2O

Mg + 2HNO3(极稀)＝Mg(NO3)2 +H2
